Hereinafter, specific implementations of the lens shading structure and the lens shading assembly provided in the embodiments of the present application will be described in detail with reference to the accompanying drawings.

According to a first aspect of the embodiments of the present application, referring to fig. 1 and fig. 2, fig. 1 is a schematic overall structure diagram of a lens shading structure provided in the embodiments of the present application, and fig. 2 is a top view of fig. 1. The embodiment of the present application provides a lens shading structure 10, including: light shield 100 and clip assembly 200.

Specifically, in the embodiment of the present application, the lens shading structure 10 can be used to be installed in front of a lens of a camera or a video camera and block harmful light from entering into the lens. For example, in the case of backlight shooting, side light shooting, or flash shooting, the lens light shielding structure can prevent non-imaging light from entering the lens, and can avoid imaging fog; or, when shooting with direct light or side light, the scattered light around can be prevented from entering the lens; when the lighting shooting or night shooting is carried out, ambient interference light can be prevented from entering the lens. Thereby effectively improving the imaging quality.

Optionally, the light shield 100 may be made of metal, hard plastic, or soft plastic.

Specifically, the fastening assembly 200 is located inside the light shield 100 and elastically connected to the inner wall of the light shield 100; the clip assembly 200 is used to abut on the peripheral wall of the lens to mount the light shield 100 on the lens.

It can be understood that the light shield 100 cannot block the lens when the lens is shielded; therefore, the light shield 100 is generally provided as a cylindrical or horn-shaped opening that matches the shape of the lens, and the light shield 100 is mounted on the peripheral wall of the lens. In the embodiment of the present application, the fastening assembly 200 is disposed inside the light shield 100, so that when the fastening assembly 200 is mounted, the fastening assembly is located between the light shield 100 and the peripheral wall of the lens and abuts against the peripheral wall of the lens 100, so that the light shield 100 can be fixed on the peripheral wall of the lens.

Specifically, in this application embodiment, buckle subassembly 200 and lens hood 100 elastic connection specifically can be through material connection buckle subassembly 200 and lens hood 100 that foam-rubber cushion, silica gel pad etc. can take place deformation, like this, when lens hood 100 receives the striking or collides, the energy of collision can be absorbed to materials that foam-rubber cushion, silica gel pad etc. can take place deformation, can weaken the impact force of conducting to on the perisporium of camera lens to can effectively protect the camera lens not damaged.

In some possible ways, the clip assembly 200 may be a spring tab protruding from the inner wall of the light shield 100.

In the embodiment of the present application, the snap assembly 200 is elastically connected to the inner wall of the light shield 100, and the snap assembly 200 abuts on the peripheral wall of the lens, so that the light shield 100 is mounted on the lens. Thus, when the light shield 100 is collided or impacted, the buckle assembly 200 elastically connected to the light shield 100 can displace to absorb part of the impact force or impact force, and the impact force transmitted to the peripheral wall of the lens can be weakened, so that the lens can be effectively protected from being damaged.

It can be understood that, in the embodiment of the present application, since the light shielding cover 100 is fastened on the peripheral wall of the lens through the fastening assembly 200, the light shielding cover 100 can rotate relative to the lens in the circumferential direction through the fastening assembly 200, so that the light shielding angle of the light shielding cover 100 can be adjusted, and the light shielding cover is adapted to different application scenes, thereby increasing the application range of the light shielding cover 100.

Meanwhile, since the clip assembly 200 is elastically connected to the light shield 100, when the light shield 100 is rotated, the clip assembly 200 can move in the radial direction of the lens shading structure, and the lens cannot be jammed, so that the light shield 100 can be rotated more smoothly.

Optionally, in this embodiment of the application, the number of the snap assemblies 200 may be two or more, when there are two snap assemblies 200, the two snap assemblies 200 may be disposed at two ends of the diameter of the light shield 100, and when there are a plurality of snap assemblies 200, the plurality of snap assemblies 200 may be uniformly arranged along the circumference of the light shield 100. Like this, the stability that lens hood 100 and camera lens are connected can be effectively guaranteed through a plurality of buckle subassemblies 200 and camera lens joint to lens hood 100, has effectively guaranteed the shading effect.

Further, referring to fig. 3 to 5, fig. 3 is an isometric sectional view taken along line a-a in fig. 2, fig. 4 is an exploded structural view of a lens shading structure provided in an embodiment of the present application, and fig. 5 is a partially enlarged structural view at B in fig. 4. In the embodiment of the present application, the clip assembly 200 includes a clip member 201 and an elastic member 202, one end of the clip member 201 abuts against the peripheral wall of the lens, and the other end of the clip member 201 is connected to the elastic member 202; the elastic member 202 is located between the engaging member 201 and the light shielding cover 100, and the elastic member 202 is used for connecting the engaging member 201 and the light shielding cover 100.

Specifically, in the embodiment of the present invention, the engaging member 201 may be made of metal or hard plastic material. As previously mentioned, the elastic member 202 may be a deformable material such as a sponge pad, a silicone pad, or the like.

In some specific examples, the resilient member 202 may be a compression spring. One end of the compression spring can be fixedly connected with the clamping piece 201, the other end of the compression spring can abut against the inner wall of the light shield 100, when the light shield 100 is connected to the lens, the peripheral wall of the lens acts on the clamping piece 201, and the compression spring is compressed, so that the compression spring can be conveniently installed on the lens; after the installation is completed, the compression spring applies a restoring force to the engaging member 201 toward the peripheral wall of the lens, so that the engaging member 201 can be tightly abutted on the peripheral wall of the lens 201.

Optionally, in order to facilitate assembly of the compression spring and the engaging member 201, in this embodiment of the application, a connecting column may be disposed on one side of the engaging member 201 facing the compression spring, the connecting column is fixedly connected (for example, integrally formed or welded) with the engaging member 201, and the compression spring is sleeved on the periphery of the connecting column. Therefore, when the buckle assembly 200 is assembled, the compression spring can be directly sleeved on the connecting column, and the assembling efficiency can be improved.

Alternatively, in the embodiment of the present application, the elastic member 202 may also be a spring plate, a coil spring, a torsion spring, or other deformable components.

It can be understood that, in order to ensure the overall aesthetic appearance of the light shield 100 after being mounted on the lens, and to prevent a large gap from being formed between the light shield and the peripheral wall of the lens, the light shielding effect is improved. Referring to fig. 4 to 8, fig. 6 is a side view of a lens shading structure provided in an embodiment of the present application, fig. 7 is a cross-sectional view taken along a line C-C in fig. 6, and fig. 8 is a schematic partial enlarged structural view at D in fig. 7. In the embodiment of the present application, the light shield 100 includes: the installation cavity 101, the buckle assembly 200 is installed in the installation cavity 101, and the one end of the catch 201 that deviates from the elastic member 202 extends to the outside of the installation cavity 101 along the radial direction of the light shield 100, and the catch 201 can move along the radial direction of the light shield 100 in the installation cavity 101.

It will be appreciated by those skilled in the art that the light shield 100 is generally a cylinder or cylindrical structure surrounded by a plurality of light shield blades, and the mounting cavity 101 may be formed extending inwardly from an inner wall of the cylinder or cylindrical structure. For example, a bump is extended inward from the inner wall of the light shield 100, and a mounting cavity 101 is opened in the bump.

Alternatively, the mounting cavity 101 may be integrally formed with the light shield 100, or may be formed by opening the light shield 100 in a secondary processing manner after the light shield is formed.

It can be understood that, in this embodiment of the application, an avoiding opening may be formed on one side of the mounting cavity 101 facing the lens, and after the engaging member 201 is mounted in the mounting cavity 101, the engaging member may extend to the outside of the mounting cavity 101 from the avoiding opening and abut against the lens.

It is understood that one end of the elastic member 202 abuts against the engaging member 201, and the other end thereof may abut against the side wall of the mounting cavity 101.

Through molding installation cavity 101 on light shield 100 to with buckle subassembly 200 setting in installation cavity 101, like this, can play better guard action to buckle subassembly 200, and also can improve the complete and pleasing to the eye of light shield 100 outward appearance.

Since the engaging member 201 moves in the radial direction of the light shield 100 in the mounting cavity 101, the engaging member 201 is prevented from moving outside the mounting cavity 101 due to the elastic member 202 (e.g., a compression spring) pushing the engaging member 201 too much. Referring to fig. 4 and 5, in the embodiment of the present application, blocking walls 2011 are provided at two ends of the engaging piece 201 along the circumferential direction of the installation cavity 101, the blocking walls 2011 abut against the inner wall of the installation cavity 101, and the blocking walls 2011 are used for limiting the engaging piece 201 in the installation cavity 101.

It is understood that the blocking wall 2011 may be integrally formed with the snap member 201; in some optional manners, the engaging element 201 may be molded first, and then the two ends of the engaging element 201 are provided with the escape notches, so that the middle portion of the engaging element 201 can extend to the outside of the mounting cavity 101, and the two end portions of the engaging element 201 along the axial direction of the mounting cavity 101 are blocked by the side wall of the mounting cavity 101.

In this way, when the lens light shielding structure 10 is detached from the lens, the engagement member 201 can be prevented from being pulled out of the mounting cavity 101 by the lens blocking the engagement member 201.

In some possible ways, to facilitate the connection or the disconnection between the engaging member 201 and the lens, referring to fig. 5 and 8, in the embodiment of the present application, a guiding surface 2012 may be provided on a side of the engaging member 201 facing the lens.

The guide surface 2012 may be chamfered or rounded.

Optionally, in this embodiment, one side of the engaging member 201 facing the lens may be provided with an arc shape, and extend a certain length along the circumferential direction of the lens. Thus, the contact area and the contact tightness of the engaging piece 201 and the peripheral wall of the lens can be increased, so that the engaging piece 201 and the peripheral wall of the lens are connected more stably.

It can be understood that when the lens shading structure 10 is mounted on or dismounted from the lens, the peripheral wall of the lens pushes the engaging member 201 to move the engaging member 201 in the mounting cavity 101. In order to avoid the situation that the clamping piece 201 shakes when moving, or the situation that the clamping piece is blocked in the installation cavity 101 by the side wall of the installation cavity 101 after moving over.

As shown in fig. 4 and fig. 5, in the embodiment of the present application, a first limiting member 1011 may be disposed in the installation cavity 101 along the movement direction of the engaging member 201, the first limiting member 1011 is located on one side of the blocking wall 2011 that deviates from the engaging member 201, and the first limiting member 1011 abuts against the blocking wall 2011, so that the first limiting member 2011 may guide the movement direction of the engaging member 201 in the installation cavity 101, thereby avoiding the situation of shaking when the engaging member 201 moves, and ensuring the stability of the movement of the engaging member 201.

Further, in the embodiment of the present application, a second limiting member 1012 may be further disposed in the installation cavity 101, where the second limiting member 1012 is located on a side of the engaging member 201 away from the lens; the second limiting member 1012 can be used to limit the moving distance of the engaging member 201 in the installation cavity 101.

In this way, the engaging piece 201 can be prevented from moving excessively in the mounting cavity 101 and being caught by the side wall of the mounting cavity 101.

Optionally, in this embodiment of the application, the second limiting member 1012 may be a reinforcing rib fixedly connected to a corner of the bottom wall and the side wall of the installation cavity 101, so that the second limiting member 1012 can also reinforce the bottom wall and the side wall of the installation cavity 101 while limiting the moving distance of the engaging member 201, and the strength of the installation cavity 101 is ensured.

As mentioned above, in some implementations, a connection post may be disposed on a side of the engaging member 201 facing the elastic member 202, and the elastic member 202 is sleeved on an outer circumference of the connection post. Thus, the second limiting member 1012 is required to be able to avoid the connecting column, so as to ensure that the engaging member 201 can move effectively. Referring to fig. 5, in the embodiment of the present application, an avoiding slot may be formed in the second limiting member 1012, and the connecting column may be inserted into the avoiding slot.

Of course, in some possible implementations, there may be an escape notch formed between two ribs.

Alternatively, referring to fig. 5, the second limiting member 1012 extends along the radial direction of the light shield 100, and the elastic member 202 is disposed in the second limiting member 1012.

In particular, the resilient member 202 may be disposed within the aforementioned escape notch. Like this, dodge the notch and can play the guide effect to the elastic component, guarantee that the elastic force that elastic component 202 provided to fastener 201 is stable on same direction, can further guarantee the stability of fastener 201 butt on the lens perisporium.

It will be appreciated that, after the snap assembly 200 is installed in the mounting cavity 101, the mounting cavity 101 needs to be closed to ensure the integrity and the aesthetic appearance of the light shield 100, and therefore, referring to fig. 4 and 8, in the embodiment of the present application, the light shield 100 further includes a closing member 102, the closing member 102 is covered on the mounting cavity 101, and the closing member 102 is used for closing the mounting cavity 101.

Specifically, in the embodiment of the present application, the closing member 102 may be a ring structure. Referring to fig. 4, the closing member 102 may be connected to the mounting chamber 101 by a screw, a bolt, or a bolt. Specifically, a connecting stud is arranged in the mounting cavity 101, and the connecting stud is provided with a threaded hole; through holes are then provided in the closing member 102, and screws, bolts or bolts are passed through the through holes and threaded holes to attach the closing member 102 above the mounting chamber 101.

Alternatively, the through-hole in the closure 102 may be a counterbore. In this way, the ends of the screws, bolts or studs can be sunk into the counter bores to ensure a smooth surface of the closure member 102.
